KNIFE, CUTTER,OR DIElNG-OUT INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 709,008, dated September 16, 1902. Application filed December 9, 1901. Serial No. 85,294. No model.

or relating to knives, cutters, or dieing-out ins'truments or tools employed for cutting, stamping, or dieing out blanks for the various parts of boots, shoes, leggings, parts of harness, tickets,labels,and other articles from the many different materials used in the various classes of business.

The objects of our improvements are to red uce the weight, and consequently the cost, of

material, and at the same time increasing the 1 strength of such instruments or tools after being formed from lengths of-steel and so that they will better withstand the wear and tear and to greatly facilitate the holding or gripping of such knives, cutters, or dies whether held by the hands of the operator or used in machines or presses.

We attain these objects by the means herein described, and illustrated in the accompanying drawings, in Which-"- Figure 1 is a side view of a deep-sole-cutting die, the corrugations orindentations being made in the direction of the length of the material. Fig. 2 is'a view in perspective of a heel-cutting die; and Figs. 3 and 4 are sections, respectively, of the corrugated or indented material and the ordinary or present method.

In carrying out this invention the steel for forming such knives, cutters, or dies A is prepared by such means as rolling or pressing the corrugations or indentations D either in the direction of its length, as shown, or otherwise or any combination of bars and ribs as may be best suited to the material. Said ribs maybe on the outer or both Walls of the material, if desired. It is well known that a die or cutting instrument in the form of a sole, with a beveled cutting edge, has been long employed, but in such knives as now made from wide strips of steel and known in the trade as deep knives when placed under the press cannot be manipulated by the operator. So by making one or more ribs or corrugations in the material this end is at tained.

What we desire to secure by Letters Patent and claim is- A die, cutter, or dieing or cutting out instrument A having ribs, corrugations or indentations B on its outer walls, and its cutting edge in line with the interior Walls thereof, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two-subscribing witnesses.
